Formula
Step-by-Step Example
Convert 5 ft²/h to pound-force seconds per square inch:
We need to convert square feet per hour to pound-force seconds per square inch
Since 1 lbf·s/in² = 267172368.09 ft²/h, divide by 267172368.09
5 ÷ 267172368.09 = 1.8714510171e-8
5 ft²/h = 1.8714510171e-8 lbf·s/in²

About These Units
Square Foot per Hour (ft²/h)
Square feet per hour (ft²/h) equals 0.258 stokes or 25.8 centistokes. Used for slow-flowing, high-viscosity materials like heavy oils, asphalt, and polymer melts. Provides convenient numbers for very viscous fluids. One ft²/s = 3,600 ft²/h.
Pound-force Second per Square Inch (lbf·s/in²)
Pound-force second per square inch (lbf·s/in²) equals 6,895 Pa·s—very high viscosity scale. Equal to one reyn. Used for extremely viscous materials: pitch, tar, and high-pressure lubricant calculations. Water is only 1.45×10⁻⁷ lbf·s/in².
